To'aZZ whom it may concern:

Be it known that we, JOSEPH-Paura and 'GUs'rAv F. llociinrmncitizens of the United States, and residingr at Chicago,in the county `5 of Cook andlState of Illinois, have invented certain new and useful Improvements. in

Coin-Controlled Mechanism for lie-.im-

.Scalesof which the follovvingis a specification.

This invention relates to coin controlled 4mechanisms which are joined to weighing scalesin such manner that certain determinedoperat-ions and the deposit of a com "are requisite before a record or register' can -be' 'obtained of the weight of a person or thing `on said scales.

The object ofthis invention is to obtain a coin controlled mechanism which is not.

liableto get out of order and which may be ro 4vided with weighing beams, having sli iup,r

weights thereon, in such manner that noY record or register of the weight of. a person l201' thing on the plat-form of the scales is obtainable until a.v coin has been deposited in the lace provided therefor and certain prescrid operations have thereafter been comlete p A further object of the invention is to ob- 'tain a device of the kind described which will not interfere with the operation of the scales or affect the accuracy of the weighing accomplished by the scales.

A further object is to obtain a device of the ,character described which will. not of itself tend to getsaid-scales out of order and will not' more than one personor object on the de posit ot' a single coin."

(liber objet-ls smight by'us are set forth in the description-and claims.

ln applying this device we have used scales 'which are provided with a base, a standout and a head, the said base, having herein a weighing frame mounted in the ordiuaryray on ,veighing levers., the said stalul-ardfliilovr :and having therein a longi-` tudinally.; movable Vrod and the' saidy head havinO* a scale beam with two members ex.-

t) n a s posed to view, mounted in the ordinary way vand provided with sliding weightsg the said longitinlinally movable rod connected ab at its lower end to the weighin r"levers and at its upper end to the scale 'ieam in the ordinary way, to transmit. motion of the weighing frame which is mounted on the levers to the scale beam. 6'5 ln the drawings referred to Figure 1 is a perspective of a Weighingscales with the device embodying our invention ap lied thereto. Fig. 2 is a frontelevation o vthe head of the weighing scales having our device applied thereto, with a portion of the front taeof said head removed to expose to view the'portion of the device embodyin oui-invention which 'is located in saidhea Fig'. 3 isanedge View. of a plate which is 75 attached to thel head of. the scales 4and ofl a. vertically movable rod mounted on "said plate, Showing a small portion of two of the members of the weiglxing beam in elevation. Fig. d is a front elevation of the plate and rod which are illustrated in Fig. 3, showing the two members of the scale beams ,l irl;8 section. Fig. 5 is a frontfelevation of4 t ort-ion of the mechanisms embodyin` -our invention which are located in -th`c hea .in their initial or normal position, with the scales not in use. Fig. 6 is a front elcj vaticn of `the several parts illustrated in Figs.- 2 and, with the' movable parts moved into a. determined position by a person or thing on theweighing platform of the scales prior to or after the deposit of a coin in the slot. of the device, but pri/or to the depression of the thumb pieceyof `the device. Fig. 7 a front elevation of the mechanism illustrated in Figs 2, 3 ande, with the' movable parts thereofinoved into a. determined osition by a' person or thingy on the weigiing 10o platform of the scales subsequent tothe deposit of a coin in the slot of the device i ing platform of the scales subsequent to the 'deposit of a coin in the slot of the device,

the depression of' ,thel thumb lever, and the release of saidthumb lever und its return to its initial position. Fig. 9 is a rear eleva-- tion of the mechanism illustrated in` Figs. Q, 5, 6, 7, and S, with the movable parts thereof in the same position as is illustrated in Fig. 5. Figs. 3 to 9 both inclusive, are on an enlarged scale from Figs. l, 2.

A Similar letters refer to similar parts throughout the several views. 4

X is the base, Y the standard and Z the head of the scales to which we have applied our invention.

. Y is the connection joined at its lower end to the weighing lever of the scales and at its upper end (see Fig. 2), to the. weighing beam.

Z, Z, Z, are members of the weighing beam, and' are provided With sliding weights inthe ordinary way.

The connection Y is the ordinary connection between the weighing levers of a scales and the weighing beam thereof and the weighing beam, mounted as sho-wn and provided with members Z', Z, Z is welll known and forms no part of our invention. i

As no change is required or made by us in the mounting of these parts of a scales We can apply the device embodying our inventio'ntoany' weighing scales of the type' illustratedl As we do not desire the scales to which our device is applied to be adjusted (for accuracy) by the person usin the same, we

y lmount the adjusting screw `Z on member Z of the weighing beam so that it is rotatable, (see Fig. 2), and non-rotatably mount the adjustingwveight Z on said member Z, and on said screw Z. 'Screw Zmfis 'not movable longitudinally, while weight j Z is movable longitudinally. Turning the screw Z, therefore, slides the weight l ZW to accurately adjust thescales. 1

The operation of'the :'lev'er D occurs without reference to the dei fpositof a coin iii slotF, by the downward 60 movement of ruil Y, .to have the end thereof with which the .upper end of said rod is shownjin engagement in Fi s. 2 5. 6 and .sntlicient strength to hold the part d 4osaid y `The rod Y is connected at its lower endl, to vthe platform A of thescales to which our' ing.v `The operations required are,"tliej'` .e-

E is a lonvitudinally movable rod, haring its upper end E in a horizontal plane,which is longitudinally movable in bearings e, e', on plate E (see Fig. 3). The upper end E of connection E is in a horizontal plane toextend under member Z of the weighing beam and'rests on bearing e" when in its. lowest position, so that said rod E is not at such time supported by end d of lever D. )Vlien platform A is iii its normal position the weighing beam is balanced but may be closed to end E of rod E, as is illustrated in Figs. 3 and 4. lhen the end d oflever D is moved up, in the manner hereinbeforef described, the free ends of all the members record or register any weight of the person et or thingr on the platform A.

As the weighing beam of the scales isl open to a person operating the device and scales, (for the purpose of sliding the Weights on members Z and Zmfon the weighing beam, to obtain the correct weight of said person or thing) the free end o f'said weighing beam may when raised by rod E with a person standing on platform A, be

forced down manually vand it ibs to avoid breakage or injury to anyl part ofthe device or scales in @se said free end of the weighing beam isforced down, that" the lever D is made in two parts. Spring al is of leverl) in its determined position'relative to the fulcrumed part of saidlever butyields to permit the end d to be forcedfddwn by the forcing down of the free "end 'of the weighing beam. l. .Y

The de pression of thumb piece G and its return to its initial fposition after the predetermined travel is obtained, may be 4mode by a person on the platform AA, as well before o, deposit. of a coin in -the slot F as after Stich deposit; but when said depression and return occur before the deposit of a com the position of lever D is not ofectedthereby, and no record or registerof the weight of the person on said platform can be ob tained. To obtain the return of the lever D to its initial and normal position upon the depression of the'thumb piece G and its return to its normal position, and While a person remains standing on the platform A, (with longitudinally Inovobieconnoction Y down), iveV provide the following elements` Longitudinally movable bar or boltli/lwhich is provided with slots m, m, and projections m, m, and mounted on the front face of plete 71. by projections m, m,-(\vhich We make integral with said platte) the said projections extending into tlie slots m, and the length of said slots permitting the determinedlength of travel of soidlboi't. Longitudinal movement of bolt N is'obtained by the projection m on said bolt M ,being positioned in the recess 1" at the lower end" "U" Sliding bar N, which is )rovideei with slots n, n., and is mounte on the plate it by the projections n', n', (which -we also make integral with the plateV on the beck fece thereof) which extend into the slots n, n. ,The sliding bar NAk isV also provided with the projection N and head N. Fles lil extends beek of the bock faceof bor Ninto-theiplece of leveigK, see Fig. 9m K' 'to reise the end lil"4 of seid level' K. Head N is provided with e vertical slot (indiooted by broken lines Nm) Figs. 5, 7, and 9. o is n plate which is rigidly secured to said sliding bar N in position to lie in o plane ernllel to thefront fece of plete z and ata suitable distance therefrom to obti o runway between 'it and the said: plate liff a coin from falling below the plates 7J `and n when said plate n is in its initia position. Theplate a is provided with a i slot or recess into which the forward end ot the bolt M moves when no coin is in the 'runway between the plates t, n, andin Jfront ot' the said recess. The upper end of the connection Y is extended through the vertical aperture, in head N, fitting loosely therein. lVhen a person is standing on the platform A with the lever D in the position illustrated in Fig. 5, and a coin is deposited in slot F, the depression of the thumb piece G moves the lower end of arm to the left, (as viewed in Fig. and the coin is' forced against the plate a forcing Said coin and plate to the lett. The coin is carried o of the projection '0, and the end y of connection Y is carried to the left and oit' from the end D ot lever 1D, at such time the endof arm l will be underneath the projection J, as in Fig. 7 and said lever D is maintained in its raised position by said projection resting on the said upper end of the arm I. The rear end ot the head N on sliding bar N is moved by the movement of said bar, out from under the end K of lever K,`allowing said lever to drop into position with the shoulder /c thereon back of the projection N on bar N, and said bar is thereby prevented from returning to its initial and normalposition, (see Fig. 7). The spring i is extended, and the several parts are in the position which is illustrated in Fig. 7. lith the several parts last above described in the position illustrated in Fig. 7 the thumb piece may be allowed to return to its initial and normal position, and it will' be so returned, it released, by spring 2'.. On the return of the thumb piece to the position thereof which is illustrated in Fig. 8 the end of arm I which is shown in Fig. 7 under projection J is moved to the left, as "viewed in said ligure and out from under said projection J as shown in Fig. 8 and the lever D may, and will, drop by gravity to its initial position, with said projection in front of arm l.` lVith the several elements of said mechanism inthe position illustrated in Fig. 3 the person standing on the platform A may move the sliding weights on beam members Z and Z of the weighing beam to indicate the exact weight which is on said platform. While vthe person remains standing on saidplattorm the lever K will continue to hold bar N in its forward or .advanced position, (by the shoulder 7c being back of lug N), but on said person 60 stepping ott1 the platform the connection Y will move upward and the end 1/ striking the underneath side of end K of lever K, will raise said nd K to release the shoulder la and projettion N from engagement, 65 whereupon the bar ll will be returned to its Leccese normal position by spring l), and the severall parts will be in the position thereof which is lillustrated in Figs. 2 and 5, and the device is in position' to be again used, as before.
